The work focused on the preparation and characterization of porous composite material as novel adsorbent towards CO2. The porous composite material was synthesized by cross-linking of cellulose and β-cyclodextrin with epichlorohydrin (EPI). Then the adsorption characteristics of carbon dioxide on the porous composite material, such as adsorption capacity and selectivity were experimentally investigated. The experimental results showed pulp cellulose in selected types of cellulose was more suitable for the synthesis of CO2 composite adsorbent. Meanwhile, the analysis from BET and FTIR indicated that the β-cyclodextrin was grafted pulp cellulose by epichlorohydrin. The grafted cellulose led to the surface area and pore size of β-cyclodextrin increased by 3.78 and 2.96 times. Compared with CO2 adsorption capacity of 3.186cm3/g on the β-cyclodextrin, EPI/PC-CD composite exhibited a higher capacity of CO2 adsorption(8.613cm3/g) at 298K and 1bar, accompanying an endothermic process and the isosteric heat between 72 and 78kJ/mol. Moreover, the adsorption selectivity of CO2 over N2 retained above 13 at 298K.
